The post-connect SET still seems like the best choice to me.
It's mildly annoying that that won't help for log_connections
messages, but in the big scheme of things that's really not a
killer problem.

The retry approach is not too bad from a user perspective: it would
only actually happen during a server version mismatch, which isn't
*that* common.  My recollection though is that there's no graceful way
to implement a retry in libpq; you'd need a significant amount of new,
ugly, special-purpose code, with the complexity rising very fast if
there's more than one reason to retry.  If you can figure out a clean
implementation this one would be okay with me, but I'm dubious that
it's worth the work.

That options hack was just an ugly hack, I don't like it at all ---
mainly because I don't believe that approach scales to solve more
than one case either.
